Description

Technical Field

[0001] The present invention relates to an earplug tip, and more particularly to an earplug tip having a variable softness. Background Art

[0002] An earplug tip generally refers to a cover body covering the front end of a headphone. The purpose of the design is to improve the wearing comfort of the user, and the earplug tip can further absorb external noise and enhance the user's listening experience. Earplug tips are usually made of soft materials such as silicone. However, in order to connect with the headphone, a certain hardness still needs to be maintained. Such hardness may cause a certain degree of discomfort to the user, especially for Asians or women with relatively curved, narrow ear canals. However, if a softer material is used, the structure of the earplug tip may not be maintained and collapse, and the overall softness of the earplug tip may also make the user feel that it is easy to fall out and have a sense of panic. Summary of the Invention

[0003] The purpose of the present invention is to solve various problems of the existing earplug tips, and to propose an earplug tip having a variable softness.

[0004] To achieve the above purpose and other purposes, the present invention proposes an earplug tip, which includes: a central support part, in a columnar shape; and umbrella leaves, surrounding and covering the central support part. The umbrella leaves include a first part and a second part. The first part has a first hardness, and the second part has a second hardness less than the first hardness. The upper end of the first part is connected to the top end of the central support part, and the lower end of the first part overlaps with the upper end of the second part to form a transition zone.

[0005] Optionally, in the transition zone, the thickness of the first part gradually decreases from top to bottom, and the thickness of the second part gradually increases from top to bottom.

[0006] Optionally, the joint surface between the lower end of the first part and the upper end of the second part is an inclined surface.

[0007] Optionally, in the transition zone, the lower end of the first part is located outside the upper end of the second part.

[0008] Optionally, in the transition zone, the lower end of the first part is located inside the upper end of the second part.

[0009] Optionally, the length of the transition zone is 2 to 3 times the thickness of the umbrella leaf.

[0010] Optionally, the lower end of the first part is joined to the upper end of the second part.

[0011] Optionally, a reinforcing structure protruding from the surface is provided inside the second part.

[0012] The present invention further provides an earplug tip, which includes: a central support portion, in a columnar shape; and an umbrella leaf, which surrounds and covers the central support portion. The upper part of the umbrella leaf has a first hardness, the lower part of the umbrella leaf has a second hardness smaller than the first hardness, and there is a transition zone between the upper part and the lower part of the umbrella leaf, and the hardness of the transition zone is between the first hardness and the second hardness.

[0013] Optionally, the hardness of the transition zone changes progressively.

[0014] Thus, the earplug tip of the present invention overcomes multiple problems of the prior art, can maintain the strength of the earplug tip, enable users to have a sense of security when wearing, and the softer second part adheres to the ear canal wall to enhance the comfort of users.

[0041] In order to fully understand the present invention, through the following specific embodiments and in conjunction with the accompanying drawings, the present invention will be described in detail. Those skilled in the art can understand the purpose, features and effects of the present invention from the content disclosed in this specification. It should be noted that the present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not drawn according to actual dimensions. The following embodiments will further detail the related technical content of the present invention, but the disclosed content is not intended to limit the claims of the present invention. The description is as follows:

[0042] As Figure 1 shown, the earplug sleeve 100 of the first embodiment of the present invention includes a central support portion 1 and an umbrella leaf 2.

[0043] As Figure 2 shown, the central support portion 1 is columnar. In this embodiment, it is a cylinder, but it can be a square column, a polygonal column or a column of other shapes. The central support portion 1 serves as the support structure of the earplug sleeve 100 and can be hollow and sleeved on a headphone (not shown in the figure), or a connecting portion of other shapes and structures to be correspondingly connected to the headphone. In other embodiments, the central support portion 1 can also be solid and used as an independent earplug.

[0044] The umbrella leaf 2 surrounds and wraps the central support part 1. The umbrella leaf 2 includes a first part 21 and a second part 22. The first part 21 has a first hardness, and the second part 22 has a second hardness less than the first hardness. In this embodiment, the first part 21 and the second part 22 are respectively made of two different hardnesses of silica gel. However, the present invention is not limited thereto, and other suitable materials can also be used. In this embodiment, the hardness of the first part 21 is 40 degrees Shore hardness, and the hardness of the second part 22 is 20 degrees Shore hardness. The 40 degrees Shore hardness can maintain the structure of the earplug 100, and the softness of 20 degrees Shore hardness is sufficient to fit flat against the skin so that the user hardly feels the wearing. However, the present invention is not limited thereto, and the hardness of the material can be appropriately changed.

[0045] The upper end 211 of the first part 21 is connected to the top end of the central support part 1, and the lower end 212 of the first part 21 overlaps with the upper end 221 of the second part 22 to form a transition zone 23.

[0046] On the premise that the thickness T of the umbrella leaf 2 remains unchanged, the transition zone 23 has both the first part 21 and the second part 22 at the same time. Therefore, the hardness of the transition zone 23 is neutralized by these two kinds, and the actual hardness is between the first hardness and the second hardness.

[0047] The setting position of the transition zone 23 just matches the ear canal wall G of the human ear, so that the transition zone 23 abuts against the ear canal wall G with a relatively moderate soft hardness and a small range, so that the human ear will not feel uncomfortable due to too hard hardness. At the same time, the hardness of the first part 21 that does not directly contact the human ear is still retained to maintain the structure of the earplug 100. And the hardness of the transition zone 23 is between the first hardness and the second hardness, giving the user a certain degree and a small range of touch feelings, so that the user has a sense of security when wearing. The remaining second part 22 then adheres to the ear canal wall G to enhance the comfort of the user.

[0048] In summary, the earplug 100 of the present invention overcomes multiple problems of the prior art at the same time: maintaining the strength of the earplug 100, increasing the comfort of the user, and enabling the user to have a sense of security when wearing.

[0049] Furthermore, as Figure 2 shown, in this embodiment, in the transition zone 23, the thickness of the first part 21 gradually decreases from top to bottom, and the thickness of the second part 22 gradually increases from top to bottom. In other words, the proportion of the first part 21 gradually decreases, and the proportion of the second part 22 gradually increases, so that the hardness of the transition zone 23 changes gradually.

[0050] In this embodiment, the joint surface of the lower end 212 of the first part 21 and the upper end 221 of the second part 22 is an inclined surface F, with an inclination angle θ. The inclination angle θ is preferably 15 degrees to 40 degrees, more preferably 20 degrees to 25 degrees.

[0051] In this embodiment, the length of the transition region 23 is 2 to 3 times the thickness T of the umbrella leaf 2. Preferably, the thickness T of the umbrella leaf 2 is between 0.4 mm and 0.45 mm, and the height of the transition region 23 is 1 mm.

[0052] In this embodiment, in the transition region 23, the lower end 212 of the first part 21 is located outside the upper end 221 of the second part 22. However, the present invention is not limited thereto. For example, Figure 3 As shown, in the second embodiment, in the transition region 23, the lower end 212 of the first part 21 is located inside the upper end 221 of the second part 22. Both methods can make the hardness of the transition region 23 change progressively. However, the present invention is not limited thereto.

[0053] The umbrella leaf 2 of the third embodiment of the present invention can also have changes such as Figure 4 : The lower end 212 of the first part 21 is joined to the upper end 221 of the second part 22. In other words, the overlapping form of the lower end 212 of the first part 21 and the upper end 221 of the second part 22 of the present invention is not limited to the intersection of the inclined plane F, and can also be other overlapping structures and forms.

[0054] Furthermore, in the first embodiment of the present invention, as Figure 2 shown, a reinforcing structure 223 protruding from the surface is provided inside the second part 22. The reinforcing structure 223 can be, for example, the three rings shown in the drawing, or more rings (such as five rings), or in the form of cross-shaped ribs, arranged convex points, etc. The reinforcing structure 223 can prevent the softer second part 22 from shrinking and maintain a strip-like form connected to the lower end 212 of the first part 21.

[0055] As Figure 5 shown, the present invention further provides a fourth embodiment. The earplug sleeve 100a of the fourth embodiment includes a central support portion 1 and an umbrella leaf 3. The central support portion 1 is the same as the central support portion 1 of the first embodiment, so it will not be described in detail here.

[0056] The umbrella leaf 3 surrounds and wraps the central support portion 1. The upper part 31 of the umbrella leaf 3 has a first hardness, the lower part 32 of the umbrella leaf 3 has a second hardness less than the first hardness, and there is a transition region 33 between the upper part 31 and the lower part 32 of the umbrella leaf 3. The hardness of the transition region 33 is between the first hardness and the second hardness. The transition region 33 can achieve a hardness between the first hardness and the second hardness by the aforementioned structural means, or can be made of a material with a hardness between the first hardness and the second hardness. The hardness of the transition region 33 can change continuously and progressively, or can be a stepped change, or no change.

[0057] For example, the hardness of the transition zone 33 can vary from a continuous Shore hardness of 39, 38, 37 degrees... from above all the way to nearly 20 degrees, or the transition zone 33 can be further divided into several bands with different hardnesses from top to bottom, which are 35 degrees, 30 degrees, 25 degrees respectively, or the hardness of the transition zone 33 itself is 30 degrees.

[0058] The earplug sleeve 100a of the present invention can achieve the same effects: maintaining the strength of the earplug sleeve 100, increasing the comfort of the user, and enabling the user to have a sense of security when wearing.

[0059] The present invention has been disclosed above with preferred embodiments. However, those skilled in the art should understand that the embodiments are only used to depict the present invention and should not be construed as limiting the scope of the present invention. It should be noted that all equivalent changes and permutations to the embodiments should be set to be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the content scope defined by the claims.
